Graph functions, build geometry constructions, explore 3D, solve with a CAS and set up a class — in one suite that runs in the browser, like the calculator suite you already know.
Pick an app to start. Constructions, settings and account carry across them.
No download, no account — open and go.
Each card opens a real construction in Graphing or Geometry — click any point and drag it. Nothing is saved to an account, so you can experiment freely.
A full math workspace — and the classroom tools around it.
Every object is defined by its inputs. Drag a point and the measurements, angles and dependent objects update live.
Functions, equations, inequalities, parametric curves, conics, sequences, sliders and shaded regions.
A CAS for symbolic algebra, calculus and linear algebra — with numeric results beside it.
Twenty distributions, confidence intervals, tests, charts and regression from your own data.
Short links with view, interact or edit rights, a password, an accent colour and an embeddable applet.
Classroom activities, assignments, exam mode, printable worksheets and seven interface languages.
Type or tap. Use the on-screen keyboard or type commands straight into the algebra input.
Keyboard first. Real shortcuts for undo, select all, the algebra, spreadsheet and CAS views.
Kept on your device. Everything runs in the browser; your constructions stay in this browser.
